New Systems Instruments Discrete Map Eurorack Sequencer Module

A New Systems Instruments sequencer was always a mouthwatering prospect, and Discrete Map is just as brilliant and unique as we'd hoped! Offering a lot more than conventional sequencing duties, it's exactly why we love modular and we reckon adventurous synthesists will love it.

Discrete Map is designed to integrate sequencing with modular time, the natural motions of your modular system, allowing for new, organic methods of composition, control, and generation. It is designed from the ground up for finer control and more complex synchronizations than a conventional sequencer can produce, and for use in generative autonomous patches.

The lower section sets 8 rising or falling thresholds, and whenever the X input signal crosses those thresholds, the corresponding stage is activated. There is also a second mode for the lower sliders, where the sliders control the relative length between thresholds instead of the absolute position of those thresholds. The upper section controls the f (X) voltage that each stage produces when that stage is activated. For situations where these thresholds are purely temporal, the internal clock provides a ramp wave as an ideal means to transform time into voltage.

At its most basic, Discrete Map creates a repeating measure or phrase, where the lower sliders control either the position or the duration of each note, and the upper sliders control the pitch. However, when integrated with other elements of your modular system, the operation of Discrete Map can become arbitrarily complex. In a given patch, Discrete Map can be set up to behave as:

• An LFO-synced sequencer
• A responsive event generator
• A quantizer, harmonizer, or chord generator
• A 16 or 24 step sequencer (with two or three Discrete Maps)
• A gate sequencer (with the A / B / C expander)
• A sequential switch (with the A / B / C expander)

Discrete Map runs directly on logic circuits, and does not contain a conventional DAC/ADC or microprocessor. Consequently all parameters operate at audio rate without a limiting sample rate or bit depth. At audio rate, uses include:

• A graphic VCO with 7 octaves of temperature compensated tracking
• A waveshaper / bitcrusher
• A VCO with phase modulation (with the A / B / C expander)
• A temporal mixer (with the A / B / C expander)

Fundamentally, Discrete Map transforms (maps) continuously moving signals into a series of discrete events. Taking inspiration from Hegelian philosophy, Discrete Map introduces dialectical sequencing to the modular system. While conventional sequencers are based on a hierarchical model where the idea determines the performance, dialectical sequencing imagines the sequencer as a tool for placing compositional elements between interacting signals.
